ATENT OFFICE 7 Claims.

My invention relates more particularly to hangers for the conventionalbaggage car doors or doors of mail and combination club doors andparticularly of the sliding type; the invention having for its objectthe provision ofa construction whereby minute adjustments maybe made andsuch adjustments be practically permanentline 4-4 `of VFigure l.

ly maintained, while the maintenance costdue to proper register with thedoor openingwill be materially reduced.

The invention has for its object the provision ci av hanger ofcomparatively simple construction A which may be easily applied andreadily adjusted tof-bring the door into complete register with theYdoor-opening and thus provide a substantially weather-prooi closurewithout resort to improper pressure and hence undue strains. I Theobjects and advantages of my invention will all be readily comprehendedfrom'the detailed `description of the accompanying drawing wherein:

Figure l illustrates a pair of my improved hangers, in front elevation,shown applied to a door and top rail of which merely portions 'areshown.

Figure 2 is a side view of my improved hanger.

Figure 3 is a vertical sectional view taken substantially on the line3-3 of Figure 1.

Figure 4 is a cross sectional view taken on the The specific embodimentof the invention as disclosed in the drawing comprises a roller carryingand rail lapping member or casting Il] of proper width and length toextend from the top or supporting rail II, which is suitably secured tothe car wall or side immediately above the door openingarid toward oneside thereof in the usual manner; the cross-sectional configuration `ofthe rail being shown in Figure v3. One leg or side of the channel rail II constitutes a trackway for th roller I2 which is journaled on thepintle or pin I3 which is removably secured in place.`

' "The upper end of the casting or member I0 is of width greater thanthe diameter of the roller I2 and is of chambered rectangularcross-section as shown at Ill in Figure 4; the upper end of the castingIll constituting a housing for the iianged roller I2, open at top andbottom.

The rear wall of the housing I4 is apertured to receive the non-threadedYend oi the pintle or `pin I3; while the front wall is made of increasedthickness or provided with'a boss and this boss portion provided with atapped opening to receive'the enlarged threaded end I5 of the pintle 13;e end i6 of the pintle I3 beyond the threaded portion I5 is shownrectangular in cross-section so as to lit into a correspondingly shapedslot or opening in a pintle holding plate or locking member I1. Y

The ends of the plate or locking member I1 are each provided with atapped hole adapted to be brought into register with tapped holesarranged in the-front wall of the casting or member il! on oppositesides Vof the pintle receiving hole. After the pintle i3 is insertedthrough the hole `in the front wall and through the hub or hole in theroller, plate or locking member I1 may be applied to the rectangular ornon-circular end` I6 of the f pintle and the plate used in lirmlyscrewing the threaded portion of the pintle i3 into the tapped bossportion of the front wall of the casting ID and after the pintle isentirely screwed into place with its inner end in the hole in the rearwall, the pintle with locking plate Il is turned to a Apoint where thetapped holes in the plate il will register with the tapped holes in thefront wall of the casting l0; the plate being then secured in this'adfjusted position by inserting screws I8, I8 through the plate Il.

With plate or locking member I'I secured in proper place by screws I8,I8, it is apparent that rotative or unscrewing movement of the pintle,due to the rolling action of roller I2 will be impossible, althougha'dismantling of the'rrroller carryingfelement may be readilyaccomplished if occasion should require.

The forward o-r outer face of the casting ID, intermediate of the topand the bottom, is formed with an outwardly disposed boss I9 providedwith a tapped opening to receive the threaded end of the bolt 26 whichpasses through the eye of the eye-'bolt or adjusting screw 2|. Y

The lower end of the casting l0, at a slight distance beneath the bossI9, is provided with a vertically disposed slot 22 `ofpredeterminedlength and arranged in alignment with the boss lll, as shown in Figure1.)

' To the rear "of the skirt or slotted lower portion of casting I is adoor engaging plate or anchor member 23, which is adapted to be securedto the door 24 in any suitable manner as by screws 25 see Figure 3. Theforward face of the anchor member 23 is provided with a verticallyelongated boss 26 which is adapted to slidably t into the slot 22 in thecasting or roller carrying member I0; and this boss 26 in turn isprovided with an outwardly extending lug 21.

The lug 21 is intended to extend outwardly a distance sufficient tobring the vertical opening through the lug into vertical alignment withthe pivot screw Z and therefore into position to receive the dependingeye-bolt or screw 2|, see Figure 3.

The threaded portion of eye-bolt 2! is provided with adjusting nuts 28,28; one of the nuts being threaded onto the bolt before the latter isinserted through the hole in the lug 2'! of the anchor member or plate23, while the lower nut 28 is then screwed onto the bolt 2i and this nutpreferably locked in its adjusted position in any suitable manner as bymeans of a lock-nut 29.

As shown in Figures 1 and 3, the vertically elongated boss portion 26 ofthe door anchor member 23 is of length considerably less than the lengthof the slot 22 in the roller carrying plate or casting I0, thuspermitting relative adjusting movement between door anchor 23 and theroller carrying plate l0.

Where the door hanger is used for the large sliding doors of a baggagecar, it is usual to employ at least a pair of hangers, as shown inFigure l, adjacent opposite ends of the door; and if desired the rearlower part oi" the casting i@ may be provided with a pair of verticallydisposed serrated ribs or flanges, as at 3U, arranged on opposite sidesof the door anchor receiving slot 22 in the casting i6; the serrationsbeing adapted to effect slight frictional relation with the face of thedoor 24 and thus somewhat assist the door anchor 23 in holding the door.

The application of my improved hanger and the mounting of the door on anoverhead rail may be readily accomplished by assembling the roller asheretofore described and locking the pintle I3 against accidentalmovement induced by the repeated back and forth rolling of the rollersalong rail Il; then apply the roller carrying element to the overheadrail Il. The anchor members or plates 23 are then vertically secured tothe door so as to register with the slot 22 in each roller carryingmember or casting I0 and the lug 21 disposed through the slot 22.

The eye-bolt 2 i, with the upper nut 28 screwed thereon, is theninserted through the hole in the lug 21 and bolt 29 passed through theeye of the bolt and screwed into the tapped hole in the enlarged or bossportion I9 of the roller carrying plate or casting lll. With the bolt 2Din place, the lower nut 28 is then screwed onto the end of the doorsuspending bolt or member 2l until it engages the lower face of the lug27. After the lower nut 28 has been screwed lengthwise of the doorsuspending bolt 2| until the door has been raised from the floor and atthe same time will freely t the door opening, lock-nut 2S is thenapplied to the bolt 2| and the upper nut 28 screwed downwardly into firmcontact with the top of the lug 21. v

Member I0 is shown provided with vertically elongated slots 3l, onopposite sides of slots 22, adapted to loosely receive bolts withwashers as at 32; the bolts being secured to the door. This permitsvertical adjustment between door and member IG to be made whileassisting the boss 26 against lateral movement.

With the elongated boss 26 of anchor member 23 slidably fitting into theslot 22 in the roller or bearing carrying member, it is evident thatlateral or sidewise movement between the door and the hanger member Il!will be impossible and a positive relation between the door and rollercarrying member I maintained.

As is apparent from the construction illustrated, the door is entirelysuspended from the bolt 2| and practically micrometer or very fineadjustments can be made. With the conventional door hangers adjustmentsof a coarser nature, as for example about one-eighth of an inch, aremerely possible; whereas with my improved construction adjustments ofone-thousandth of an inch are possible and these adjustments madepractically permanent, which is not the case with the conventionalhangers due to slippage of the ratchets, permitting the door to get outof adjustment and at times making it impossible to operate.

The eye portion of the door suspending bolt 2l is preferably providedwith iiat faces so the bolt may be free to swing on the bolt 20; andinstead of the plain roller i2 it is apparent that a rollerbearing typemay be employed; and while I believe the construction shown to be thebest embodiment of my invention certain modiiications may be madewithout departing from the spirit of my invention which has beendescribed in terms employed merely as terms of description.
